Biology

Sunkern is a mostly yellow, seed-like Pokémon with a small sprout growing out of its top. It has triangular, spike-like protrusions on top of its head, encircling the sprout. Its body has three broad, brown, vertical stripes. Two of the stripes start jaggedly above Sunkern's dark eyes and continue downward. The other stripe is directly below Sunkern's mouth. Since Sunkern's eyelids are brown, the brown streak patterning appears uninterrupted when Sunkern’s eyes are closed.

Sunkern is known to be very weak. Aware of its weakness, it only feeds until it evolves. However, it feeds on only the dew from under the leaves of plants. It tries to move as little as possible, since it tries to conserve all the nutrients it has stored in its body for evolution. If attacked, it shakes its leaves at the attacker. Sunkern occasionally falls from the sky on early mornings for unknown reasons. A year after a cold summer, the population of Sunkern explodes. Sunkern can be found in grassy meadows.

A group of Sunkern appeared in Zoroark: Master of Illusions as a few of the many local Pokémon who lives in Crown City. Some took part in surrounding Zorua in the park along with the other Pokémon to prepare to attack him, angry at Zorua for what Zoroark did to the city. Before a fight broke out, the Sunkern, along with the other Pokémon, were calmed by Celebi.

In the Pokémon Adventures manga

In Sunkern Treasure, Gold encounters a herd of Sunkern escaping from a wild Skarmory. To help Falkner capture the Skarmory, Gold captures the Sunkern to use her jumping ability to get high enough and attack it. Afterward it was named Sunbo and later evolved into a Sunflora through a makeshift Sun Stone.

Sunkern tries to move as little as it possibly can. It does so because it tries to conserve all the nutrients it has stored in its body for its evolution. It will not eat a thing, subsisting only on morning dew.

Sunkern shares the same species name as Bulbasaur and its evolutions. They are all known as the Seed Pokémon.

Sunkern's official artwork more closely resembled its Shiny form in Gold and Silver than its regular form. This was somewhat rectified in Crystal, although the artwork was still more similar to its Shiny sprite; this discrepancy was fully rectified in Generation III.
